Description. ♀. Apterous; body length 2.0– 3.2 mm. Head black, except mandible, anterior region of frons and clypeus testaceous; antenna brown, except scape and part of flagellomere 1 testaceous. Mesosoma black, except pronotum brown, distal extremity of propodeal declivity and most part of mesoscutum testaceous (anterior margin of mesoscutum darkened); petiole black; metasoma black; legs testaceous, except coxae and clubs of femora partly black. Antenna clavate; antennomeres in following proportions: 6:4:10:7:5:5:5:5:4.5:6.5. Head shiny, unsculptured, except occiput granulate; frontal line complete; occipital carina absent; POL = 1.5; OL = 2; OOL = 7. Palpal formula 4/2. Pronotum shiny, bare, crossed by strong transverse impression, with collar unsculptured and disc slightly granulate. Mesoscutum granulate, without lateral pointed apophyses. Mesoscutellum unsculptured. Metanotum flat, granulate, about coplanar to mesoscutellum; sides of metanotum rounded. Metapectal-propodeal disc shiny, slightly granulate, with track of median longitudinal furrow; propodeal declivity, mesopleuron and metapleuron transversely striate. Meso-metapleural suture obsolete. Protarsomeres in following proportions: 13:3:4:12:18. Enlarged claw ( Figs 172E, F View FIGURE 172 ) with one large subapical tooth and one row of five lamellae. Protarsomere 5 ( Figs 172E, F View FIGURE 172 ) with two rows of 17–18 lamellae; apex with 5–6 lamellae. Tibial spurs 1/0/1.

♂. Fully winged; body length 1.6–1.7 mm. Head black, except mandible testaceous; antenna brown; mesosoma and metasoma black; legs brown, except tarsomeres 1–4 whitish. Antenna filiform; antennomeres in following proportions: 2:3:4:4:4:3.5:3.5:3.5:3.5:4.5; antennomere 3 less than 3 × as long as broad (4:2). Head dull and granulate; clypeus very prominent, shallowly emarginated, sticking out as bill ( Fig. 174C View FIGURE 174 ); frontal line absent; occipital carina absent; POL = 5; OL = 3; OOL = 4; vertex with two oval shiny areas situated between lateral ocelli and eyes (areas not anteriorly surrounded by high carina). Palpal formula 4/2. Mesoscutum shiny, granulate. Notauli incomplete, reaching approximately 0.75 × length of mesoscutum. Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal disc shiny, unsculptured, with median longitudinal furrow; propodeal declivity unsculptured. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (10:6). Dorsal process of paramere ( Fig. 173B View FIGURE 173 ) long and with broad apex. Tibial spurs 1/1/2.

Material examined. Types: ♀ holotype: CAPE VERDE ISLANDS: Santiago Island , São Jorge dos Orgãos, 19.XI.1985, on lucerne, A. van Harten leg. ( AMNH)   . Paratypes: same locality label as   holotype, 2♂♂ ( AMNH)   . Other material: GAMBIA: Kombo North District , Abuko Nature Reserve, 10.XI.1992, 1♀ ( ZIL)   . SOUTH AF- RICA: KwaZulu-Natal , Nhlazatshe, NNW Denny Dalton, roadside S of hill, 28°11’S 31°12’E, 1000 m, 1.XII.1999, ex emergence box with stems of Mikania capensis   , DEL 12.03, O.C. Neser, J. Balciunas & Grobbelaar leg., 1♀ ( SANC) GoogleMaps   ; Western Cape , near George, N 12- Road to Montagu Pass junction, C. 25.I.2003, B. 27.I.2003, Sf. 19.II.2003; C. 25.I.2003, B. 28.I.2003, Sf. 19.II.2003; M. Olmi reared from Syndelphax capellana (Jacobi)   , 2♀♀ ( MOLC)   .

Hosts. Delphacidae ( Guglielmino et al. 2013)   : in South Africa: Syndelphax capellana (Jacobi)   .

Distribution. Cape Verde Islands, Gambia, South Africa.

Remarks. The ♀ mesosoma of Gonatopus festivus Olmi   can vary in colour, from totally testaceous to partly black or brown. If the colour is partly black or brown, ♀♀ of G. festivus   can be confused with G. harteni Olmi. In   this case, ♀♀ of these two species are indistinguishable. However, the two species are distinct, because their ♂♂ show strong differences.
